Recommend me a best & safe heic to jpg converter for my Win 11 PC

Recently I encountered a problem. I have nearly 1,300 photos in HEIC format on my computer, but I need to convert them to JPG format because I need to edit and share these photos, and many platforms do not support HEIC format. I have tried some online tools, but the conversion speed is slow, and some will compress the pictures, resulting in a decrease in image quality.

So I was wondering if I could find a better HEIC to JPG converter, preferably one that can be used directly on the PC, does not require an Internet connection, and can maintain the image quality. Does anyone have similar experience and can recommend a good tool? I hope it can be converted in batches, and the operation is simple, preferably without ads and watermarks. Thank you everyone!
